Application of modern methods for production of mobile phone storage stand
Tesař, Jaroslav ; Nejedlý, Jindřich (referee) ; Sedlák, Josef (advisor)
The thesis was made as a bachelor’s project on Faculty of Mechanical Engineering, Brno University of Technology. In the theoretical part methods of Reverse Engineering were described. The principle of the following technology, the Rapid Prototyping, was also explained and the summary of advantages and disadvantages and use in technical practice for the most important methods was made. In the experimental part of the thesis the modern methods were applied for manufacturing a cell phone holder. By this the possibility of these technologies to work with complexly shaped models was verified. The casting to a silicon form was used as the alternative method of manufacturing. The summary of possibilities of manufacturing with these technologies and technical and economical evaluation were made in the end of the thesis.

RP technology using FDM method and investment casting technology
Kosour, Vojtěch ; Krutiš, Vladimír (referee) ; Horáček, Milan (advisor)
An overview of the development of the Investment Casting market and Rapid Prototyping equipment is given in the introductory part of this diploma thesis. Basic methods of rapid prototyping and the FDM method are futher described in detail. The FDM method is consequently used in the practical part of this work for the preparation of the silicon mould. The largest part deals with the issue of the simulation of pouring process of wax into the silicon mould. A characteristics of the casting wax is made; the parametres, which are inserted into the simulation software ProCAST and the possibilities of their measurement are described. The process of the simulation of the mould filling and its validation with the real filling process are described in detail.

Possibilities of using modern methods in manufacturing of prototype castings
Šmíd, Jiří ; Horenský, Jiří (referee) ; Horáček, Milan (advisor)
The introduction part of the thesis focuses on the overview of rapid prototyping in foundry industry. Principles of the most important RP methods are described and the FDM method is analyzed in more detail. This method was used in the practical part for the production of wax patterns with silicone moulds. The wax patterns were used for the production of castings using the lost wax method. The result of this work is determination of dimensional changes during the whole process of casting manufacture from the drawing to the final casting.

Application of Modern Technologies in Production of Bathroom Accessories
Kudela, Jan ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The aim of this bachelor thesis is to design and manufacture prototypes of selected bathroom accessories. These were designed via 3D parametric modelling in Autodesk Inventor software. CAD models were then 3D printed at Dimension uPrint printer using today’s most common additive technology – Fused Deposition Modelling. A conventional silicon mold was also created as a part of this thesis using printed prototypes and other set of designed accessories was created by resin casting. The conclusion of this thesis is comparison of printing and casting manufacturing processes of these bathroom accessories from the technological and economical point of view and detailed evaluation of used technologies.

The Design and the Possible Practical Application of a Cooking Pot Handle 3D Model
Bezděk, Adam ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The target of this bachelor thesis is designing and producing of a 3D model cooking pot handle with use of the modern 3D printing technologies. The virtual model of the cooking pot handle was produced with parametric program Autodesk Inventor and then printed by the Dimension uPrint 3D printer, which uses the Fused Deposition Modeling additive technology. The silicone mold was produced by using the printed master model. Then the model was molded from the two component plastic material into the silicone mold. Conclusion of this work contains technical-economic evaluation, where are both methods of producing the model compared.

Application of Rapid prototyping for production of historical models of assault force vehicles
Malý, Ondřej ; Sedlák, Josef (referee) ; Dvořáček, Jan (advisor)
The paper deals with the production and subsequent evaluation of produced historical trolleys Steyr K2670 models at a scale of 1:120. For manufacturing of the product was used rapid prototyping technology, which creates objects based on the virtual designs. In order to compare, the prototype model was built on different machines, using different methods of making bodies. Based on the final product was produced 3D printing silicone mould, into which was casted the modeller resin in the vacuum chamber. The conclusion is that for objects with very fine detail, it is suitable to choose a machine with high accuracy, working with thin layers of material. The prototype needs to be shaped before creating mould because silicone mould transmits most of the details, such as the texture of the surface layer structure.

Prototype Part Design Using the Reverse Engineering Technology and Rapid Prototyping
Luňák, Václav ; Sámelová, Vendula (referee) ; Slaný, Martin (advisor)
This Bachelor thesis is dealing with the manufacturing process of a motorcycle turn signal part using the technologies of reverse engineering and rapid prototyping. The thesis contains a brief description of the available technological methods. The following chapters deal with designing the component and its preparation for casting. The component is manufactured using the FDM method. The quality check is performed by the ATOS 3D scanner, which compares the newly manufactured component to the original part. The next step is the preparation of a silicone mold, which is used to cast more parts. Finally, the cost-effectiveness of this method is compared to the method using metal molds.
